Have you tried very low carb diets? I maintain a strict keto diet (<20g carbs/day), and when I'm in ketosis the hunger impulse is almost entirely gone. I'm very active - I train Brazilian jiujitsu and lift - and despite that, there are days that I'll just forget to eat because I'm not hungry unless there's food in front of me.
My brain is absolutely addicted to sugar, though, and if I start eating it I get just insatiably ravenous. The combination of sugar/fat/salt together is a perfect storm of "put all that into my face and don't stop until there's no more left" brain chemistry triggers, and how that's most of our prepackaged food is constructed now.
